Documentation     This module will take whatever action is necessary
...               to bring the BMC to a stable, standby state.  For our
...               purposes, a stable state is defined as:
...                  - BMC is communicating
...                   (pinging, sshing and REST commands working)
...                  - Power state is 0 (off)
...                  - BMC state is "Ready"
...                  - HOST state is "Off"
...                  - Boot policy is "ALWAYS_POWER_OFF"
...               Power cycle system via PDU if specified
...               Prune archived journal logs
